Gotland (older spellings include Gottland or Gothland Gutland in the local dialect) is Sweden's largest island. It also is a province, county, municipality, and diocese. The province includes the islands of Fårö and Gotska Sandön to the north, as well as the Karlsö Islands (Lilla and Stora) to the west. The population is 58,595, of which about 23,600 live in Visby, the main town. The island of Gotland and the other areas of the province of Gotland make up less than one percent of Sweden's total land area. The island's main sources of income are agriculture, food processing, tourism, information technology services, design, and some heavy industry such as concrete production from locally mined limestone. From a military viewpoint, it occupies a strategic location in the Baltic sea. As of 2018 the Gotland Regiment has been re-raised and it is the first time since World War II that a new regiment has been established in Sweden.
